I know that dovetails are the strongest joint for drawer construction. But I didn't want to spend $$ on a jig just now. What's the next best thing? I have a table saw and router. I'm using 1/2 inch Baltic birch plywood. 7"H,38"W,21"D. False front. Full extension side mount drawer slides. The drawers will be used for DVD storage on a built-in entertainment cabinet - not very heavy contents.
